Evaluation of new industry standard Epson LQ-690KII needle printer

Different from today's inter enterprise alliance first out standard, in the embryonic stage of the IT industry, each enterprise will rely on its own excellent product quality and reputation, many outstanding products will stand out and become the de facto industrial standard Needle printer This is the product.

In addition to the exemplary products, Epson's most important contribution is the Epson Standard Code for Printer, abbreviated as ESCP. This code system is used to drive Needle printers and inkjet printing products. Epson also optimized for Chinese. Epson launched ESCP/K. Now, needle printers and thermal printers on the market still use this code for output control.

As the originator of needle printer, Epson launched LQ-690KII This new product aims at the demand of bills and small size paper production. Let's take a look at the characteristics and performance of this product.

The window industry urgently needs

Today, many window industries, such as banks, telecommunications, postal services, hospitals, etc., have various demands for bills and small size paper. The size of the card is very small and hard. Only the stylus printer can meet this demand at a low cost.

Epson LQ-690KII has made targeted optimization for bills and small size paper, which is reflected in two aspects. First, it can support the normal push of 90X60mm cards. Secondly, Epson LQ-690KII has two paper feeding modes, one is friction feeding, which is traditional, and the other is paper feeding from the rear paper holder to ensure compatibility. The combination of these two points makes Epson LQ-690KII easy to handle different needs.

Durable and high-speed is the key

Epson LQ-690KII is a 24 pin printer with 106 column output function. It can output 274 Chinese characters per second and 487 characters per second for 10 cpi English under the condition of one gear high speed and 7.5 cpi (CPI=charaterperinch, characters per inch) Chinese. For the commonly used multi copy bill printing, Epson LQ-690KII can easily complete the output of 1+6 to ensure that the sixth copy is also clear.

Such high speed must be combined with durable consumables. The needle life of Epson LQ-690KII has reached 400 million times, the average time between failures has reached 20000 hours, and the ribbon can support 20 million characters.

Ease of use reduces barriers to use

In order to ensure product compatibility, Epson LQ-690KII is configured with two traditional parallel ports and USB interfaces. USB allows this product to connect many new Software Environmental Science. Epson LQ-690KII ribbon replacement is very simple. With the clip design, it is very easy to complete.

On the control of the fuselage, there are three speed indicators and locking/paper shortage indicators above the panel. The following four keys are the most commonly used functions of Epson LQ-690KII. The physical keys of the entity are convenient for users to use, including paper cutting/certificate, line and page changing, paper advance and retreat, etc. A paper control rod is embedded in the lower right side of the fuselage, which will not be touched incorrectly, nor will it easily become dusty or dirty.

If not, the paper feed tray of the Epson LQ-690KII can be turned up because its body optimizes the volume and occupies very little space on the desktop.

Diversified feeding: manual setting is required

In consideration of different output purposes, Epson LQ-690KII can print consecutive multiple documents, single page paper or cards. The paddle on the right side of the fuselage is used to set whether to print single sheet paper or use the paper holder to print continuous paper.

Card printing is a difficult test project. We also cut out 90mmX60mm small cards for printing test. According to ISO-7810, the card specification of ID-1 is 53.98mm and 85.6mm long. The small card function of Epson LQ-690KII just covers the size of ID-1 card. This kind of printing must be customized in the print driver. Epson LQ-690KII can see that in order to realize the automatic paper feeding/card feeding of this card, a paper take-up wheel is specially set in the left area.

Text print quality

Epson LQ-690KII has three gears, called high-speed 1, high-speed 2 and letter quality mode. Here we compare their output speed and quality.

We specially bought 1+7 multiple sheets, which are more than the official ones of Epson, to see the penetration quality of the different layers. It should be noted here that the number of layers penetrated needs to be set by the right paddle on the printer. The "Copy" mode in the print drive cannot guarantee the penetrability. In the actual measurement, we can still clearly identify the small 5 and 5 characters on the eighth page of 1+7, the small 5 or 6 characters on the seventh page, the small 6 to 6 characters on the sixth page, and the small 7 characters on the fifth page. In fact, no one can print such a small font when printing bills. This penetration capability is enough to print and penetrate ordinary multiple copies of documents. Even if LQ-690KII penetrates one more copy, the eighth page is more recognizable than the official page.

Under different printing speed settings, we find that the color depth of the printed handwriting is somewhat different from the set printing speed and penetrability. In brief, the slower the set printing speed and the higher the set penetrability are, the darker the printed handwriting will be. There is a feeling that the text is "thickened". This requires users to set the printer according to the actual use needs, and it is good to see clearly enough, because the darker the setting is, the faster the consumption of consumables will be. Users need to find their own output quality and cost balance point.

Test summary: small and easy to use without fear of industry test

The penetrability of needle punching makes it active in various document printing fields for a long time and has a very long life force. As a benchmark product, Epson's LQ-690KII enjoys a high reputation in the field of flat pushing and continuous paper bills. LQ-690KII is a product that has been optimized according to market feedback and has more output capacity of small cards in function.

From the perspective of actual measurement, in addition to easily meeting the output demand of traditional multiple bills, Epson LQ-690KII has also targeted the optimization of small cards and thick cards. Combined with good ease of use, this product has become a product that can be quickly used by all users, which is not easy for an industrial product.

Epson has worked in the field of needle printers for more than 40 years from the launch of early models such as LQ-1600K to today. The excellent product quality and bottom drive make Epson's products become the de facto industrial standard, which has won Epson numerous praises. However, Epson is not complacent. Instead, it has launched a wide range of needle punching products to meet the needs of various sub industries. With excellent product quality and refined targeted products, it has built up the trust and dependence of users on Epson needle punching.
